Abstract:
23 sulfated alkanolamides with high purity were synthesized by the sodium catalyzed reaction of methyl esters of fatty acids with alkylolamines, the sulfation of the alkanolamides with chlorosulfonic acid and the neutralization of the sulfated products with alkali such as sodium hydroxide, ethanolamine etc. The surface active properties of the sulfated alkanolamides were determined thoroughly and the relationship between chemical structures and properties were investigated. The study showed that most of the sulfated alkanolamides have good foam height and lime soap dispersing power.
